Question about tire and wheel fitment.

[NDsuperduty]

With my 6" lift and bumper replacement I have room to easily clear 37's, but my 35's rub the radius arm at full turn. Does anyone know what offset I would need to fit 37's without rubbing?

Also, if I were to install bushwacker cut outs would I be able to fit 38's? if so does anyone know the offset needed for that?

Thanks in advance.

Are you looking to run a 37x12.50 or 37x13.50?

A 37x13.50 on a 9" wide wheel with 5.50" backspacing (+14mm offset) is our usual recommendation, and will just barely rub the driver's side radius arm. Not enough to be a problem, but they do contact. We suggest this fitment because it minimizes the scrub radius, and keeps the tires tucked, as much as possible with such a wide tire.

A 37x12.50 on the same wheel will generally clear, depending on the manufacturer.

If you prefer a wider stance, a +0mm offset will give more clearance on the radius arm, moving both tire outboard 1/2". Although many folks run them, we do not generally suggest a negative offset, as at that point you are significantly increasing the stresses on the bearings and ball joints.

Thanks,

I have a 6" on my 2012 with 20x10 -19mm Ballistic Rages with 37x13.50's and they have no rub at full lock either way
